unix network programming book code has bugs due to old OS, how to solve this or where to get new code ?

I am trying to download and run the c code on Linux for

UNIX Network Programming, Volume 1, Second Edition: Networking APIs: Sockets and XTI, Prentice Hall, 1998, ISBN 0-13-490012-X. It is by W. Stevens Richard

 http://kohala.com/start/unpv12e/unpv12e.tar.gz

But, when I build the code, I got error: 

  gcc -g -O2 -D_REENTRANT -Wall   -c -o connect_nonb.o connect_nonb.c
  In file included from connect_nonb.c:1:
   unp.h:114: error: redefinition of âstruct in_pktinfoâ
   make: *** [connect_nonb.o] Error 1

I commented out struct in_pktinfo. Then I got new errors: 

   gcc -g -O2 -D_REENTRANT -Wall   -c -o in_cksum.o in_cksum.c
   gcc -g -O2 -D_REENTRANT -Wall   -c -o inet_ntop.o inet_ntop.c
   inet_ntop.c: In function âinet_ntopâ:
   inet_ntop.c:61: error: argument âsizeâ doesnât match prototype
   /usr/include/arpa/inet.h:67: error: prototype declaration
   make: *** [inet_ntop.o] Error 1

I do not want to debug for the whole 575 files one by one.

Where can I get new code without these errors ? the new version book has bug-free code ?

The old code is only for old OS.

Thanks

well, The Author Richard Stevens passed away in 1999 and the Book is still the a very good reference. You can't say this about a lot of more than 10 year old technical references.

I just fetched the source from http://www.unpbook.com/unpv13e.tar.gz and followed the readme, which basically meant to run ./configure and call make in the directories 

/lib
/libfree
/intro

I fixed a single place (libfree/inet_ntop.c:60 and changed size to socklen ) and it compiled on my current Ubuntu. I didn't run it, but I trust that at least the most of it will work.

Richard Stevens books are still outstanding and worth the small effort it needs to keep his sources running.
